PATENTED JAN 2 21974 SHEU 5 [IF 7 W nmv omv PATENTEDJAN 22l974 SHEET 6 BF 7 sel, and has particular application to a portable device of the general class described which lends itself readily to over-the-road transport from one location to another at which latter place it can be quickly re-assembled for service as a rotating ride; and concerning which carrousel I provide marked flexibility in the selection of its plane of rotation as concerns both its angular vertical attitude and its height above the ground in horizontal plane. As well, my invention provides for certain flexibility, as concerns both the vertical and the horizontal, in the positioning of the assembled carrousel with re spect to the trailer on which it is mounted and which trailer provides, in assembly, the base or mounting frame of the device.

Thus it will be seen that an object of my invention is to provide a rotating-wheel or carrousel type of amusement device which, capable of ready over-the-road transport from one location to another and lending itself to ready, simple, certain and rapid procedures in both 'disassemby and assembly, at the same time provides a high degree of flexibility in the disposition of the assembled rotating wheel with respect both to its vertically-angular relation to the ground and its mean height thereabove.

Another object is to provide an amusement device of the general type described wherein, while the rotating device is in passenger-carrying operation, the operator thereof can quickly and rapidly accomplish multiple changes in the orientation of the rotating wheel and this, both with respect to vertically angular attitude and with relation to its instantaneous, mean height above ground.

Another object is to provide an amusement device of the general class described wherein is employed a rotating wheel the precise location of which latter, in operable assembly, readily lends itself to wide range of selective choice on the part of the operator; which device is markedly simple in construction, at the same time wherein, illustratively, I disclose a presently preferred embodiment of my invention.

And now, having particular reference to the several views of the drawings;

FIG. 1 discloses in side elevation, the amusement device designated for convenience by the general term carrousel, as that name may be broadly interpreted, and shown in its entirety with included trailer, the carrousel being dismantled for over-the-road transportation;

FIG. 2 is an elevational view somewhat similar to FIG. 1, parts being broken away for simplicity and disclosing the device in assembly, with the rotating wheel in one of its myriad positions;

FIG. 3 comprises a still further side-elevational view showing the carrousel in assembly, with the assembled gondola-carrying spider positioned for rotation about a vertical axis and a considerable height above the supporting trailer bed;

In FIG. 4 I disclose one of the sweeps in elevational detail, a number of whichsweeps are assembled to form the rotating wheel or spider assembly;

The bearing assembly for carrying the related passenger gondola comprises the subject matter of FIG. 5, it being noted that there is one such bearing assembly between each related pair of sweeps it being further noted that there is one gondola associated with each such bearing assembly;

FIG. 6 is a plan view of the sweeps as related both to the sweep-carrying axle assembly and as well, to the sweep-connected drive track and gondola-carrying hanger assemblies;

FIGS. 7 and 8 are plan and side elevational views, respectively, of the drive mechanism for the rotation of the gondola-carrying spider assembly;

FIGS. 9 and 10 are respectively, a side elevational and a cut-away section, the latter through vertical plane, of one of the gondolas carried by the rotating wheel or spider assembly, clearly depicting the suspension of such gondola through the intermediary of a hanger mounted between a related pair of sweeps, and from the outer extremity of these latter; while The hydraulic system for the carrousel is disclosed schematically in FIG. 11.

F ORENOTE By way of forenote it may be recalled that more and more, the industry has been directing attention to the production of a wide variety of amusement rides which, to a certain degree, are adaptable for over-the-road transportation for short-time stays from say, one carnival to another. Many of these amusement devices are centered around a rotatable wheel from which passenger-carrying units are suspended, while similarly, much attention has heretofore been directed to imparting flexibility in the positioning of this rotatable wheel in assembly and relative to the ground, both as to (a) the particular angle or attitude with respect to the vertical in which the wheel or ride is located, and (b) the precise positioning both horizontally and vertically, with relation to rectangular coordinates, of its related mobile platform. And while some effort has been made towards permitting operator-chosen compounding of the wheel-location controls during rotation these efforts, for a number of reasons, some one or more of which such efforts relate to the presently available devices, have uniformly fallen short of complete satisfaction. In sum, neither desired flexibility of positioning nor compounding of motion during operation has been fully achieved. Moreover, these known devices involve detrimental complexity of both design and construction. In many instances they display insufficient sturdiness along with other insufficient porformance characteristics so that, all in all, difficulties have demonstrated themselves both in frequent break-down and in complexity of the requisite repairs. Finally, consumeracceptance has been notably disappointing.

- disassembled and compactly positioned and stowed for over-the-road transportation, (b) can be readily unstowed and re-assembled on new location, and (c) can thereupon be operated by relatively unskilled labor; which device, basically simple both in design and construction, nevertheless displays all requisite sturdiness and safety in operation, meeting all Code requirements of the various controlling bodies, all coupled with long useful life.

And now, having reference to the disclosure of the several views of the drawings, I note that in this presently preferred form as herein illustrated, and perhaps having initial attention more particularly to the disclosure of FIG. 1,

TRAILER ASSEMBLY An over-the-road trailer which comprises part of my construction is broadly indicated at 10. I provide this trailer with a load-distributing, tandem-mounted rear axle assembly 11. And I provide a conventional suspension system 12 which carries this axle assembly 11, thereby supporting the trailer from the under side thereof. It is to be noted that this trailer 10 typically and conventionally is made up of longitudinal trailer beams 14 disposed one on each side of the trailers longitudinal centerline, together with longitudinally extending side rails 15 carrying the trailer bed, which bed is not itself depicted in the drawings. Wheels 13, conventional in nature, are mounted to and serve to carry suspension system 12. For purposes to be discussed hereinafter, I provide lugs 15a, 150, (see FIG. 1) while I provide generally similar and upstanding lugs 15b,15b, one on each side rail 15,15 near the end thereof.

Conventionally, the frame of trailer 10 is provided with an upstanding and forwardly projecting, somewhat goose-neck extension 16. The undercarriage 17 of trailer 10 may be compartmentized for storage of equipment during transport. A series of reinforcing struts 17a depend from the side rails 15 along the lengths of these latter, being secured at various points to the undercarriage 17, preferably at the bottom thereof. Forward jack assembly 18, which in a typical embodiment and for economy, preferably is handoperated, serves when the amusement ride is in assembly and when'these jacks are lowered to the ground, as part of an effective, ultimate load-carrying and stabilizing system.

Forward bulkhead assembly 19 (FIG. 1) is disclosed as formed on, fast to and depending from the underside of trailer side rails 15,15. These elements 19 are fabricated from tubular or generally similar materials. They serve to reinforce and strengthen the assembled ride. A similar bulkhead assembly 20, designated as a rear bulkhead assembly, is suspended from the rear ends of the side rails 15,15.

These bulkhead assemblies, 19,20 respectively carry jack assemblies 21,21 and 22,22, one such jack assembly of each of the related pairs of assemblies being bolted or otherwise made fast to the corresponding bulkhead on each side of the centerline of the trailer. In FIG. 1 these jack assemblies will be seen to be telescopic in nature. They are disclosed as raised from the ground G. On the contrary, in FIGS. 2 and 3 they are disclosed as lowered to, resting upon and reacting against the ground, substantially participating and assisting, along with jack assemblies 18,18, in stabilizing the carrousel while in assembly and in passengercarrying service. Importance attaching to a high degree of stabilization, I provide these jack assemblies 21,22 as far outboard of the longitutudinal centerline of the trailer 10 as is possible. And this is also true as concerns the jack assemblies 18,18.

It is to be noted that the diagonal element 23 (perhaps best disclosed in FIGS. 1 and 3) which extend between the bed of the trailer 10 and the rear jack assemblies 22,22, is itself comprised of reinforcing braces.

Plate 24 of trailer 10 is made fast to and depends from the underside of goose-neck extension 16. This plate 24 carries pin 25 depending downwardly from the center thereof.

The better to understand the operation of these several jack assemblies, it may be noted at this point that, in preparation of the trailer for over-the-road transport a suitable tractor, not shown, is connected by means of a king pin 25 to the trailer 10, thereby imparting a limited degree of lift thereto and about the tandem wheels 13,13 of the trailer as a fulcrum. The operator then jacks up the several jack assemblies 18,21 and 22 (it being noted that in my preferred embodiment, here shown, the assemblies 21,22 are actuated hydraulically).

With the ride dismantled and compacted upon said trailer for over-the-road transport, the device is ready for carriage to its next location.

ANGULAR AND HEIGHT POSITIONING COMPONENTS As to the components mounted on trailer 10, and having attention to the disclosure of FIGS. 1 through 3, it will be seen that pedestal assembly 26 with its related and fabricated leg 26a, serves as the ultimate support and carriage for the passenger-carrying spider of my device, and which latter is itself made up of fabricated elements later to be described. To this end and at its upper, outer and otherwise free end, this leg 26a pivotally carries a spider-carrying boom assembly 2611. This boom assembly 26b itself is comprised of hollow, fabricated or built-up construction more particularly disclosed in FIG. 8, and concerning which it is here noted that, internally thereof and pivotally supported thereby, it carries a mounting frame 45 (See FIG. 3), later to be described.

In FIGS. 1 through 3 I disclose paired, loaddistributing gussets 260,260 extending between and each made fast, at one end thereof to leg 26a and at the other end to boom assembly 26b, thereby providing a rigid and somewhat monolithic pedestal 26, possessing all requisite sturdiness and displaying completely adequate factor of safety. Leg 26a terminates at its lowermost and rearmost extremity in a toe 26d. This toe 26d serves as part of a hinge element, for swinging pedestal 26 through a vertical plane and about a horizontallydisposed hinge pin 26e. This hinge pin 26c extends through lugs 15b;15b, these latter being upstanding from the rear ends of side rails 15,15.

Giving attention now to the boom assembly 26, it may be noted that at the rearward end of this latter, and about its centerline, I provide paired hinge elements and pins 26i(FIGS. 1 through 3). These serve for the pivotal reception of piston rod 270, the latter being a part of a telescopic hydraulic cylinder 27. I'make clear in the disclosure of FIGS. 1 through 3, the manner in which these hydraulic cylinders 27, of which I provide a pair, are each pivotally connected between related and paired lugs a,15a upstanding from the forward bulkhead 19, of the trailer 10, at their one ends, and the related hinge elements 26i, 26i of boom assembly 26b, at their other ends. For more complete understanding of the function of these hydraulic cylinders 27 it may be noted, giving particular attention to the disclosure of FIG. 1, that with piston rods 27c of related hydraulic cylinders 27 in retraction, the sweeps 31 (of which more will be said at a later point in this disclosure) are disclosed as pulled into their lowermost and horizontal position. Because of this and with passenger-carrying gondolas 37 carried near the ends of these sweeps (FIG. 3) all passengers may simultaneously and readily either mount upon or dismount from the gondolas, from or to an extended deck on the trailer 10, as the case may be. In this regard it is to be noted that I provide a multi-hinged deck, conventional to the art,

.which is carried in collapsed form on trailer 10 during transport, and which is assembled on location into a horizontally-extending, somewhat annular, passengercarrying deck which fits symmetrically about the assembled carrousel.

Conversely, and havingconsideration of the disclosure of FIGS. 2 and 3, and with piston rod 27 in extension, the sweeps are elevated at selected substantial heights above the ground. The angular relation or attitude of these elevated sweeps 31 with respect to the ground is controlled by additional mechanism later to be described. Mounting frame 45, shown both in FIG. 8 and the top center of FIG. 3, is pivotally and internally carried at the outer free end of boom assembly 26b. It is from this frame 45 that axle assembly 29 is rotatably carried. And it is this axle assembly 29 which serves directly to carry the sweeps 31, and on which the sweeps are foldably mounted. The details of construction of frame 45 and related components will be deferred to a later point in this disclosure. It is here noted, however, that frame 45 cannot be seen in FIGS. 1 and 2, since it is collapsed within the related boom assembly 26b. Having attention to the disclosure of FIGS. 1 through 3, it will be seen that this axle assembly 29 comprises an axle 29a which in turn, is provided with top and bottom axle rings or circular caps 29b,29c. These latter are welded fast to the axle 29a, and they extend concentrically and outwardly therefrom, as perhaps will best be seen from a consideration of the disclosure of FIG. 6.

THE SPIDER ASSEMBLY It being noted that the plurality of sweeps 31 comprise, in assembly, a spider 30, it is further to be noted that it is this spider which is directly carried by the I sweep-carrying axle assembly 29. Each sweep 31 may be likened in general configuration, to an elongated arm. And each such sweep 31 is fabricated or built-up of constructional components, to provide a completely acceptable combination of light weight coupled with requisite qualities of physical strength, displaying a high degree of resistance to failure in tension, compression, shear or any combination of two or more thereof. It may here be noted that each two adjacent sweeps 31,31 (FIG. 6) serve as a pair to pivotally carry arelated gondola-supporting means each of which latter, and in turn, suspend the related gondola therefrom, for pivotal movement with relation thereto and this, both in oscillating revolvment and in axial rotation with respect thereto.

For each sweep 31 (FIG. 6) I provide a hinge pin 31a. This hinge pin rotatably extends through the upper axle ring 29b near the outer extremity thereof. Similarly, and having reference to FIG. 8, I provide a hinge pin 31b which serves to make its related sweeps 31 rotatably fast to the lower axle ring 29c.

It being essential to make the sweeps fast to axle 29 when the device is in assembly, I provide for each sweep 31 and radially inwardly of the related hinge pin 31a, a suitable lock pin 310. This lock pin 31c passes through the related sweep 31 and makes the same removably fast to the top axle ring 29b. In like manner (FIG. 8) I provide a series of removable lock pins 31d, serving to make the sweeps removably fast to the lower axle ring 290.

On location and in assembly, the sweeps 31 are rotated about the hinge pins 31a, 31b in umbrella-like or spider-like symmetrical arrangement; whereupon the removable lock pins 31c, 31d are inserted to secure the sweeps in their spread, spider-like assembly. Conversely, and upon dismantling the apparatus preparatory to stowage and transport, the lock pins 31c, 31d are first removed. The sweeps 31 may then be folded or nested in generally parallel configuration, nested longitudinally of the centerline of trailer 10 (see the leftmost portion of FIG. 6).

For proper mounting of sweeps 31, I provide (FIG. 4) paired mounting lugs 31i, 31j. These mounting lugs project inwardly from the inner end of each sweep 31 and this, both at the top and bottom of these latter. These paired lugs 31i,31j respectively engage about the top and bottom axle rings 29b,29c of axle assembly 29. For convenience in construction, it is to be noted that I bend the bottom mounting lug 311' into a widely obtuse-angular configuration. In the assembly of the sweeps 31 into spider-like configuration, hanger rods 34a, 34a (FIGS. 5 and 6) are provided, one between each related and adjacent pair of lugs 31f,31f, these latter being carried on the adjacent sweeps31,31. More specifically, each rod 340 is hinged at one end to related lug 31f, as by hinge pin 31g, while at its other end this hanger rod 340 is made removably fast to its related lugs 31f, as by removable bolt 31h.

BEARING ASSEMBLY, FOR SWINGING SUPPORT OF PASSENGER-CARRYING GONDOLAS Anti-friction bearings, 2,2 preferably comprising combined journal and thrust bearings, are provided. One of these is disposed at each end of bearing assembly 35 (FIG. 5). These bearings 2,2 are indicated merely schematically in the drawings. To minimize the weight of this bearing assembly 35, at the same time decreasing total quantity of material required, a portion 35d thereof may be cut away in the region of the related hanger rod 34a.

Having reference more particularly to the constructional details of FIG. 5, I provide an elongated tubular member 1 extending throughout bearing assembly 35 and made fast thereto as by welding or the like. The bearings 2,2 are press-fitted, one at each end of this tubular member 1. They serve nicely to receive the related hanger rod 34a, in anti-friction manner. As will be seen, each bearing 2 terminates at its outer end in an outwardly projecting annular flange, which serves to receive and react against thethrust shoulder 1a of the related hanger rod 34a. Each bearing assembly 35 carries a gondola-carrying axle 36, made removably fast thereto as by pins 356,356. And each gondola-carrying axle 36 has suspended therefrom a related gondola 37 (FIGS. 9 and 10). For reasons hereinafter stated, this axle 36 is hollow. More precisely, hollow axle 36 is tapered near but short of its upper end for snug, frictionfit with and into a complementally-tapered block 36b. This block 36b is pierced near each end thereof for alignment with corresponding openings in bearing assembly 35 for the reception of removable pins 35e,35e. Hair-pin cotters 35f,35f serve to removably lock the block 36b in assembly. The extreme upper end of axle 36 is'threaded for the reception ofa lock-down nut 360. In its threaded-down position this lock-down nut 360 is made fast by hair-pin cotter 36f.

And now having particular attention to the construction illustrated in FIGS. 5 and 10, it will be seen that a flexible safety cable 360 extends through hollow axle 36 and is made removably fast at its upper end (FIG. 5) to bearing assembly 35 through suitable and conventional securing means 35a, with included pin and cotter elements, indicated at 35a. As will best be seen from FIG. 10, both axle 36 and its included cable 36a extend through the interior of the related gondola 37 to lowermost thrust bearing 36s.

DETAILS OF PASSENGER-CARRYING GONDOLA It may be noted at this point in the disclosure that, in operation, passengers seated at 37a,37a in the respective gondolas may provide rotational spin to any particular gondola in which they may be riding, simply by grasping the control wheel 36d and reacting thereagainst, thereby initiating gondola rotation about axle 36, in direction and at rotational speed selected by the passengers. This rotation is of course, independent as relates to each gondola 37, and may vary widely from gondola to gondola. Thus both rotational speed and direction of rotation may vary not only from one gondola to another but as well, from moment to moment with the particular gondola.

The side door 37b, vertically hinged at 37e,37e to gondola proper 37, serves to permit ready entrance and exit to the gondola. This door is provided with conventional and spring-loaded latch 376. Each gondola 37 (FIG. 9) carries anti-friction rollers 37d, 37d to facilitate movement about the platform or bed of trailer 10, or its included gooseneck extension thereof.

CERTAIN MECHANICAL ELEMENTS OF DRIVE MECHANISM At this point in the description, it is in order to disclose the manner in which the gondola-carrying sweep assembly is driven in rotation. To this end, each sweep 31 hingedly carries (FIG. 6) a related arcuate track section 32. In assembly, these track sections 32 combine to form a circular ring or track. Each section 32 is hinged at 33 by means of permanently fast hinge-pin 33a so that when dismantled, the related track section 32 will fold forwardly along the length of the sweep, along one side thereof (it is to be noted that for convenience, the hanger rods 34a are swung rearwardly of the sweeps 31 and this, along the side of the sweeps opposite that along which the track sections 32 fold). The other, free end of each track section 32 is made removably fast to the hinge 33 of the next adjacent sweep 31 (in clockwise direction as seen in plan in FIG. 6) by removable lock pin 33b. This track 32 is disclosed in section in FIG. 4, intermediate the length of the sweeps 31.

The circular track 32 comprises part of the drive mechanism, certain details of which are perhaps best disclosed in FIGS. 7 and 8. From a consideration of these views, it will be seen that frame 45 is pivotally carried on and by boom assembly 26b, through bearing assembly 26h.

FURTHER DETAILS OF DRIVE MECHANISM A drive mechanism, perhaps best shown in FIGS. 7 and 8, serves to impart rotational motion to the spider assembly 30. It will be recalled that this spider assembly 30 includes the circular drive track 32 against which paired drive wheels 41,41 frictionally react, thereby imparting spin or motion to spider assembly 30 in either clockwise or counterclockwise direction, and in widely ranging and variable speeds, all under the control of the operator. It is worthy of special note that these factors may be varied while the ride is in motion, thus facilitating production of pleasing and rapidly and continuously variable motion sensation to the riders. The relation of these drive wheels 41,41 to the track 32 is such that, upon discontinuance of positive drive to these drive wheels, hydrodynamic braking of the carrousel sets in, contributing to bringing the spider assembly to rest in smooth and rapid manner.

To this immediately foregoing end, a five-sided truncated motor-mounted plate 43 engages side rails 45a,45a of drive-system-mounting frame 45 in such manner as to be capable of limited longitudinal movement at the outer or free end of this latter. This limited movement is occasioned by linear travel of piston 44a of hydraulic cylinder 44, this piston being made fast to the adjacent and truncated top 43a of five-sided plate 43. The drive-system-mountingframe 45 is pivotally carried from boom 26b through a suitable hinge 26h. As a constructional detail, it may be noted that plate 43 is limited to longitudinal reciprocal movement by and between the side rails 45a,45a of frame 45. Plate 45b may be made fast as by welding to the side rails 45a, extending from the boom-related end thereof to a point 45b (FIG. 7) intermediate the length of these side rails. It is this plate 45b which carries hydraulic cylinder 44. And upon energization of this cylinder 44 through the hydraulic system of FIG. 11, which system is later to be described, the wheel-carrying plate 43 can be linearly moved together with its drive wheels 41,41, into and out of engagement with track 32 of spider assembly 30.

Noting that pump 38a of this hydraulic system (FIG. 11) energizes this hydraulic motor 40 (FIG. 8) it is to be further noted that the shaft 40a .of this motor 40 carries a double sprocket 40b. And drive chains 42 extend between this double sprocket 40b and related drive sprockets 41a of drive wheel 41, there being two such drive chains, one for each of these paired wheels.

In operation the hydraulic cylinder 44, through its related wheel-mounting plate 43, serves to move the drive wheels 41,41 into and out of engagement with track 32, while at desired times and durations hydraulic motor 40 imparts rotation to these drive wheels 41,41 in rotational direction and at speed, both at the selection of the operator.

The operator having energized cylinder 44 in manner such as to bring the drive wheels 41 into drive relation with track 32 (although motor 40 may not yet have 9 been brought into rotation), means conventional to the art and included in and as part of cylinder 44, thereupon serves to lock the piston 44a in its extended position.

CERTAIN DETAILS OF.ASSEMBLY,'ON LOCATION, OF STOWED CARROUSEL, PREPARATORY TO OPERATION THEREOF It is now in order to describe the operation of the mechanical components of the carrousel, as relates to the assembly thereof, on location, into condition ready for operation. Let us assume that the carrousel, disassembled and compacted for over-the-road transport, arrives on the trailer, at the location for reassembly, preparatory to operation. I

The operator first plugs in the electrical system to available service so as to energize the hydraulic system. He cranks down the jacks 18,18 (FIG. ll) into loadbearing relation to the ground and the front part of the trailer, together with its related load, is jacked up thereon. The tractor, not shown, is thereupon freed from pin 25 of plate 24. The hydraulically powered jacks 21,21 and 22,22 are lowered-to the ground and the carrousel is jacked up thereon, taking load of the trailer wheels 13,13. Suitable adjustment is made to the several jacks, so that the trailer bed is leveled into a fully horizontal plane. The passenger deck, hinged to the trailer, is then unfolded and assembled to level, passenger-loading position. This deck extends completely around the circular extent of the assembled carrousel, facilitating in loading and unloading, as the case may be, all the passengers at one stop of the spider assembly.

At this point, all sweeps 31 are unstowed and rotated into approximately their radially extending, spider-like operating position (FIG. 6), somewhat .in the manner of an umbrella; Gondola-bearing assemblies 35 (FIG. are next unstowed; and are rotated outwardly into their FIG. 6 position. They are then pinned by removable bolts 31h in their operable position.

As a next step, the track assemblies 32 (FIG. 6) are unstowed, unfolded inwardly, and pinned in place by lock pins 33b. Sweeps 31 are then locked in assembled position by inserting lock pins 310. This is followed- (FIGS. 7 and 8) by energizing hydraulic cylinder 44, operating the same to bring drive wheels 41 to bear upon track 32. v

Following this, and as the next step, is the energization of cylinders 27 (FIG. 1) and 46 (FIG. 3) to slight extent. This combined action will lower the outer ends of selected and paired sweeps'3l, together with their related and intermediately-positioned gondola bearing assembly 35, onto axle block 36b ofa related one of the stowed gondolas 37. It is to be'note that to this end, it is cylinders 27 and their related piston rods 27c which are first energized, rotating pedestal assembly26 about hinge 26e, followed by energization of cylinder 46 and extension of its piston rod 46a, causing frame 45 to swing about hinge 26h. Following this, pins 35c (FIG. 5), 35a, and cotters 35f,35f are secured in place, thereby making the particular gondola 37 fast to the rotatable spider assembly.

The sweep sequence is repeated sequentially until all ten gondolas are mounted in suspension from the spider. The assembly is now complete.

Repeating to some extent what has hereinbefore been said, it is to be noted that, under control of the oprotates spider 31 in its plane of rotation. The operator erator, motor 40 (FIG. 8) is then energized, causing rotation of drive wheels 41 through drive chains 42. This then energizes cylinders 27 to selected position in vertical angular sweep to a fixed limit, in the selected neighborhood of 62 to the horizontal, this having been computer-selected as the angle which'is optimum for loads and reactions to be maintained at a safe magnitude.

Next, the operator, at his option and either combined with operation of cylinders 27 or separately therefrom, will operate cylinder 46 (FIG. 3) to selected angle through a vertical plane which is-in thev third quadrant as relates to rectilinear coordinates, up to nearly hori- V HYDRAULIC POWER SYSTEM Having heretofore discussed the details of the mechanical system which operates the carrousel, it is now in order to give consideration to .the hydraulic system which powers these mechanical components. My resort to an hydraulic system for powering these several parts of my new carrousel permits great flexibility in the control for the several parts thereof, as will be seen from a consideration of the details of that hydraulic system. As disclosed in FIG. 11 this hydraulic system is energized from electric motor 39, which latter is jacked into available electrical service at each location at which the carrousel is set up in operable assembly. The opposed drive shafts of this electric motor 39 drive hydraulic pumps 38:; and 38b. These pumps serve to force hydraulic fluids through their related, closed hydraulic systems.

Having attention to hydraulic pump 38b it will be seen that illustratively, fluid supplied from reservoir 47 can be forced from right-hand end of pump 38b through conduits 53 and 55,-and thence to hydraulically paralleled, paired jacks 21,21 and 22,22 with related hydraulic controls 21a, 21a and 22a22a. Each jack 21 and 22 has included therein, piston rod assemblies 21b and 22b respectively. More precisely, the hydraulic fluid courses conduit 55 to paralleled conduits 56, 57, 58 59 one for each of these four hydraulic jacks just alluded to. Return conduits 60 and 61 are provided, one such conduit for each pair of jacks 21,21 and 22,22. These conduits 60,61 merge at their junction 61a into single conduit 62, passing thence through conduit 63 to reservoir 47. Fluid from reservoir 47 is led by conduits 64, 65 to the left side of pump 38b, completing the hydraulic energizing circuit for the hydraulic jacking system.

Thus energized, the jacks 21,21 and 22,22 will function to jack up vthe loaded trailer. The weight of the loaded trailer can be effectively relied upon to lower the trailer upon release of the pressure release valves of these jacks. Y

Following assembly of the spider and its included track, accomplished mechanically, the carrousel is ready for operation of the drive wheels 41, 41 in FIGS.

7 and 8. This is accomplished by passage of pressuredriven hydraulic fluid from pump 38b, through conduits 53 and 66 to control 51 for hydraulic cylinder 44 (FIGS. 7 and 8) and its related piston rod 44a, and thence through hydraulic conduit 67 extending between control 51 and cylinder 44. Conduits 68, 69 and 63 serve to complete the return system to reservoir 47, with hydraulic fluid coursing thence through conduits 64 and 65 to pump 38b.

It is now in order to rotate drive'wheels 41,41 (FIGS. 7 and 8) so as to drive the spider assembly 30. To this end, drive motor 40 (FIG. 11) is energized from pump 38a through conduit 70 to motor control 48 for the hydraulic motor 40, fluid coursing from control 48 through conduit 71 to motor 40, thence returning to reservoir 47 through conduit 72. The reservoir 47 supplies pump 38a through conduits 64 and 73.

Assuming that the operator may desire to raise the spider assembly 30 to an attitude of tilt with respect to the horizontal (although it is not required that he do so), control 50 is energized from pump 3812, thereby energizing paired hydraulic cylinders 27,27 (FIGS. 2 and 3) and related piston rods 27c,27c (as to these piston rods 27c,27c see also, FIG. 8). The hydraulic systems of the cylinder 27, and following the conventions previously adopted herein as concerns the description of these hydraulic systems, is such that fluid courses from the right-hand side of pump 38b, through conduits 53 and 54 to control 50; thence through conduit 74 to cylinders 27,27; and thence through conduits 75, 69 and 63 back to reservoir 47, fluid being thence supplied through conduits 64 and 65 to the left-hand side of pump 38b.

Finally, it being desired to raise spider assembly 30 from some initial position of this latter, the lowermost limit of which is disclosed in FIG. 1, to some point up to and including the upper and limiting, horizontal position, as illustrated in FIG. 3, I energize hydraulic cylinder 46 (FIG. 3) and its related piston rod 46a through control 49 which is hydraulically powered off pump 38b. The hydraulic system for the operation of this spider-raising cylinder 46 may be traced as follows, still having reference to the disclosure of FIG. 11: From the right-hand side of pump 38b through conduits 53 and 76, control 49, conduit 77, cylinder 46, and conduit 78 to reservoir 47, and thence through conduits 64, 65 back to the left-hand side of pump 38b.

SUMMATION OF ADVANTAGES Upon consideration of all the foregoing, it can be readily ascertained that my new construction is attended by rugged simplicity coupled with long useful life, and is further attended by a highly practical combination of certainty of operation, marked freedom from repairs, ease of such repairs as and when required, and the involvement of component parts which themselves are simple and readily available on the open market, at comparatively low cost. As well, labor and operators of but moderate skill are required, with attendant low cost of operation.

My new ride lends itself to ready and rapid assembly, once the carrousel arrives on location and is unstowed from its compacted and dismantled position on the carrying trailer which latter, on location, becomes an integral part of the assembled device, serving as the base thereof. The ride can be passenger-loaded on all of the ten gondolas at one time, and during a single stop, and

this without necessity of sequentially spotting each gondola at a common loading dock; it being noted that, within my knowledge, no device either heretofore known or presently marketed permits loading at a single stop with subsequent elevation to selected height and attitude of operation.

The carrousel can be raised to any one of a wide range of selected heights, and may be tilted to a range of something more than 60 of vertical angle to an upper, elevated and limiting horizontal position. The spider assembly 30 may be rotated at 'varying speeds in either direction of rotation. Oscillation of the passenger gondolas may be achieved through effective combination of gravity action and centrifugal force as speeds and heights of the spider are varied. Finally, the passengers in each gondola can contribute to the variety of obtainable motions through rotation of the hand wheel 36d on shaft 36 (FIG. 10).

All the foregoing, as well as many other practical objects and advantages, attend the practice of my invention as hereinbefore described and illustrated. And it will be apparent from the foregoing that many different embodiments of the basic concepts as hereinbefore described and illustrated, as well as many modifications of the disclosed embodiments, will readily suggest themselves to those skilled in the art. Accordingly, I intend the foregoing disclosure to be considered as simply illustrative, and not by way of limitation.
